Project 5.7 - Thermal Flux and Albedo Measurements from Aircraft Capt R,. L. Dresser
OPIFOTIVE
The objective of Project 5.7 participation on this shot was
to Obtain thermal flux and albedo information of a nuclear detonation with
airborne calorimeters, radiometers, and sixteen
millimeter motion picture cameras.
INSTRIMENTAT TION
Instrumentation within the purview of Project 5.7 which was
installed in the B-47 inclujed nineteen NRDL calorimeters and two
NRDL radiometers for measuring the direct and surface reflected
thermal radiation,
Six calorimeters were utilized to measure ther-
ma] radiation which was back-scattered toward the cockpit,
Seven
GSAP N-9 cameras were utilized to obtain photographic coverage of
the fireboll, the earth's surface, and of clouds beneath the air-
eraft, and also of any reflecting surface such as a cloud which could
contribute to the back-scattered radiation.
Project 5.7 instrumentation on the B-52 included the twenty-one
basic instruments for thermal radiation measurements, but only an
additional two instruments were utilized for back-scatter measurements.
Eight GSAP cameras were installed for photographic coverage.
Project 5.7 instrumentation on the B-57 consisted of the basic
twenty one instruments and six cameras,
Project 5.7 instrumentation on the B-66 consisted of the basic
